Some pregnant women find that they’re more comfortable in the woman-on-top position or side-by-side. Both of these positions allow the woman to control how deep her partner penetrates. The side-by-side position also puts less pressure on the uterus. Kneeling on all fours is another option.
Couples are encouraged to discuss what works best for them and be willing to make adjustments. Hugging, kissing, massage, and mutual masturbation can be satisfying as well.
